D'Sivas was noted as the great city state on the planet Romulus. It was noted that more visitors come to D'Sivas than any other state in the home system. Typically, these individuals come on official business to the government officers or audiences with the Emperor of the Romulan Star Empire himself. It was considered the heart and the brain of the people. The FASA material states that D'Sivas is in fact the capital of the Romulan Star Empire, however, Ki Baratan is known to be heart of the Empire in the novels.
